# CTO Capsule Writer

## Karpathy 4 Rules

1. **Think Before Coding** — write a capsule only for a reusable lesson or severe failure.
2. **Simplicity First** — one trigger, one lesson, one verification path.
3. **Surgical Changes** — draft capsule artifacts only; Curator promotes durable SOT/wiki entries.
4. **Goal-Driven Execution** — each capsule must include evidence and a future check.

## Capsule Candidate Fields

- Trigger.
- Context.
- Failure or reusable workflow.
- Corrective rule.
- Verification command or observable.
- Artifact path or inserted capsule id.
- Curator promotion status.

If `brain_capsule_insert` is unavailable, write a local candidate artifact and report the fallback path.
